Analgesic effect: by inhibiting the synthesis of prostaglandins and other substances; anti-inflammatory effect: may be by inhibiting the synthesis of prostaglandins or other inflammatory response substances; antipyretic effect: may increase heat dissipation by acting on the hypothalamic temperature regulation center; anti-rheumatic effect: in addition to antipyretic and analgesic, it mainly has anti-inflammatory effects; inhibitory effect on platelet aggregation: prevents the formation of thromboxane A2 by inhibiting platelet prostaglandin cyclooxygenase.

Inhibits the influx of Na+ and Ca2+ ions across the cell membrane, and stabilizes the cell membrane of excitable cells such as bronchial smooth muscle and inflammatory cells

Blocks bronchial smooth muscle choline M receptors and histamine H1 receptors, relaxes bronchial smooth muscle, inhibits the release of allergic mediators, and reduces capillary permeability

Stimulate beta 2 receptors, promote the release of norepinephrine from nerve endings, enhance diaphragmatic contraction, and help improve respiratory function; stimulate alpha receptors on airway vascular smooth muscle, constrict airway blood vessels, and inhibit congestion and edema

This product is a compound preparation mainly based on phenytoin sodium and contains a variety of drugs with different mechanisms of action. Its main mechanism of action is: inhibiting the influx of Na+ and Ca2+ ions across the cell membrane, stabilizing the cell membrane of excitable cells such as bronchial smooth muscle and inflammatory cells; ephedrine hydrochloride stimulates beta;2 receptors, promotes the release of norepinephrine from nerve endings, enhances the contraction of the diaphragm, and is beneficial to improving respiratory function. Belladonna fluid extract and chlorpheniramine maleate can block the choline M receptors and histamine H1 receptors of bronchial smooth muscle, respectively, and relax bronchial smooth muscle. In addition, this product also has the effects of stimulating alpha; receptors on airway vascular smooth muscle, contracting airway blood vessels, inhibiting congestion and edema; inhibiting the release of allergic mediators, reducing capillary permeability; reducing viscosity by changing mucin synthesis; promoting airway ciliary movement, and enhancing diaphragmatic contraction. There is a good synergistic effect between the components of this product. Experiments have shown that this product has a good effect on histamine and acetylcholine. It has a significant antiasthmatic effect on asthma caused by antigens, and has a significant antitussive effect on various experimental coughs. This product also has a certain expectorant effect.
